7 Claims.

My invention relates to needlework which can be made by hand by the use of a single ordinary straight, smooth needle, such as a darning needie, but may also be fabricated in quantity on any fish net machine, which may be adapted to this kind of work and design.

This knotted-loop work can be applied to many useful articles, such as curtains, bed spreads, lace collars, handkerchiefs, trimmings, sweaters, and so forth.

It may be fashioned directly into the shape of a garment, sweater, for instance, or for flat work as curtains, tablecloths and the like, when made in great lengths of uniform width and sold by the yard to be out into suitable lengths and joined together to form a square or rectangular piece.

For this needlework may be used ordinary cotton or woolen yarn, silk or linen thread and so forth.

In the accompanying drawings, the same numerals indicate the same details in the different views and Figures 1 to 5 show the progress from start to finish of the series of operations needed for making one knot-loop, and

Figure 6 indicates the beginning of a knot-loop pattern with a single loop;

Figure 7, a pattern with double loop, and

Figure 8, a pattern with small twin-loop under a large bridging-loop;

Figure 9 is a pattern for a lace-edging as applied to collars or handkerchiefs with a bridged single loop pattern;

Figure 10 is a similar pattern suitable for yard lengths with spaced parallel rows of pairs of single loops running across the net work;

Figure 11 is a pattern for yard length work with twin loops close together and having the side edges provided with bridge loops;

Figure 12 is a pattern for yard length work principally of net work foundation with rosettes or groups of four single loops placed symmetrically apart on the net foundation, and

Figure 13 is also a pattern for yard lengths consisting of spaced parallel double rows of single loops running lengthways of the piece.

It is evident that many variations and combinations of these patterns are possible all using the same method of knot-loop work.

One of the objects of my invention is now to manufacture this knotted-loop fabric of uniform width in great lengths, to be sold by the yard and cut to suitable lengths like ordinary cloth, which is possible because of the knots formed at 2 all crossings of the threads, thus preventing unraveling.

Considering first Figures 1 to 5 representing the needed operations of the method, Figure 1 shows the manner of starting to make a lace edging for a handkerchief or a collar, as finished in Figure 9, or Figure 6, numeral indicates one edge of the workpiece, which is folded over as at or in other words the material is doubled along the edge. An ordinary large smooth needle 22 is used carrying through its eye a thread or yarn This needle is pushed in at the front of the workpiece and drawn out through the edge of the fold at 24, see Figure 2, but permitting a short piece of thread 23a to remain within the fold, see Figure 3. The needle is thereupon entered a second time into the material but at a second point 25, Figure 3, passing under the thread 23 on the reverse side to form a loop 23b over the needle 22. Next the loop 23b is given a half twist and thrown over the needle point, see Figure 4, so that the advanced portion of the thread 23 nearest the needle eye passes above the loop portion 231) at 23c and below the needle at 23d and then above the latter again as at 23c. In Figure 5 is'shown the formation of the knot so that with a little more pull on the needle 23, the knot will be drawn tight over the edge of the material, care being taken to hold the work pressed between the fingers in order to prevent the thread end 23a to slip through the material.

A series of knots 26, all alike as just described and shown in Figures 1 to 5, are subsequently made of a single, continuous strand along the edge of the material as in Figure 9 followed by a second, third or more rows of knots 26a formed in similar manner until the desired plain network foundation 21, Figure 9, is obtained. This is finished ed with a series of single small loops 28 from the same strand as in Figure 6 finally terminating with a large bridging loop 25 above each single loop 28 in Figure 9 also from the same thread.

In Figure 10 is seen a pattern of knotted-loop work which consists of a net foundation 2! of yard length and uniform width, across which are formed pairs of bands or rows 30 of single loops 23 as formed in Figure 6, These rows or bands Bil are spaced at uniform intervals to produce a regular pattern.

In Figure 12 the single loops 28 are formed into rosettes 3|, symmetrically arranged on a net foundation 21. This pattern is also intended for material in yard lengths of uniform width.

Still another pattern for yard length work consisting of single loops 28 on net foundation 21 is illustrated in Figure 13 wherein the bands 32 consist of two lines each of single loops 28 running in spaced relation lengthways of the work. The loops 28 and 33 are of the ordinary kind, that is the strand is left slack between the knots, instead of stretched as tight as between knots 26a in the plain network foundation 21.

In Figure 7 is indicated the formation of twin loops 33 on the edge of the fabric and in Figure 8 such twin loops 33 beneath a bridging loop 35; while Figure 6 shows one line of single loops An exampleof a pattern incorporating this twin-loop design 33, 34 on a net foundation 2'! is shown in Figure 11, which is also intended for yard length material of uniform width. In every instance all of these patterns consist of a single strand from which the knots and loops are formed, beginning with 26 and ending with 29 or 34.

It is to be understood that the invention as here disclosed is not limited to the details here described and shown but that the same may be varied without departing from the spirit of the invention as defined by the subjoined claims.
